TO ALL WI-IOM IT MY CONGERN:

Be it known that I, JOHN G. Bonomi, ot Brewster Station, in the countyot Putnam, and State of New York, A have invented a new and improvedMachincfor Soldering Tin Cans; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, which willenable' others skilled in theart to make and use the same, referencebeingr had to the accompanying drawings, forming part of thisspeeication.

Figure 1 represents a side elevation, partly inr section, of myinvention.

Figure 2 is a vertical transverse section of the same, the plane ofsection being indicated by the line .r x, tig. 1.

Figure 3 is a plan or top view, on a reduced scale, 'of thesolder-.receptacles.

Similailetters of referenceindicate corresponding parts.

This inventinn relates to a new apparatus for soldering tin cans, or allother *metal cans which .have

round heads.

The invention consists, first, in the use of a` cast-iron plate, whichhas two depressions, one of which holds the solder, while a copper blockis placedy into the other. In'the copper block is a recess, whichcommunicates with the solder-reservoir, and as the iron plate is heatedby a re under it, the solder iiows from the reservoir into'the recess inthe copperv block, standing in the latter at a desired level. The edgeof aitin can to be soldered is placed into the recess in the copperblock, and, as the can is revolved by suitable machinery, its edge takesup as much solder as is necessary to rmly unite the head with the sid-e.

The invention also consists inthe device for holding and revolving thetin can. The same consists of a` sliding shaft, which is by 4a springheld out of gear, but which, when moved by a treadle orsuitable lever,is thrown into gear with another revolving shaft, and is thereby alsorotated. This shaft is inclined, and has a pad at its lower end, betweenwhich and `the inclined bottom of the recess in the copperblock, the canisheld, and as the pad is revolved with the shaft the can is alsocarried round.

A represents a cast-iron plate, of suitable size and shape. The same isplaced upon a stove or heating apparatus, B, of suitable construction,forming the cover of the same. Two recesses, a and b, are formed orcountersunk in the plate,A, as shown in tig. 2, both Vcommunicating witheach other by means of a. channel, c. C is a block, of copper or othersuitable material, of the sume shape and size as the cavity b, and isplaced into the said cavity so as to exactly ll the same. .A cavity, cZ,'is formed in the block C. The shape of this cavity vis like that'ot` asection of a cylinder, .formed by passing a plane, at an 'angle of aboutsixty degrees, through the base and convex side of a cylinder, thesegment of the base being less-` than half the base. The can to besoldered is of 4 the same diameter as the cylinder from which the cavityd is formed, and thus dierent blocks, C, must be used for cans ofdifferent diameters. A channel, e, leads from thecavi-ty d to theoutside of th'e block C, and vforms an extension of the channel e, sothat the cavities a and d are connected with each other. Solder isplaced into the receptacle a, and is melted by the re under the plate A,and flows through the-channel c e into the cavity d. D is an inclinedshaft, having its bearings in a stationary frame, E, the angle-which theshaft D forms with a horizontal line being about thirty degrees. Theshaft D slides on its bearings, and is by a. spring,f, thrown up, unlessit is thrown down by means of a lever, g, and treadle, F, or by anyother suit` able device. 7L is a gear-wheel, mounted on the shaft D. Gis a horizontal or other shaft, having its bearings in the frame E, andreceiving rotary motion by means of 'a belt passing-overa pulley, jis' agear-wheel, mounted upon the shaft G. W-hen the shaft D is thrownl up'by the action of the spring f, thewheels t and j are not in gear witheach other, butwhen the shaft D is drawn down by means of the treadle F,.the wheels t and j will mesh into cach other, as shown inig. 1, androtary motion will thereby be imparted to the shaft D.

At the lower end of the shaft is secured a ilat disk, H, having aleather or rubber covering, K. i

The can to be soldered is placed against the disk K H when the shaft Dis up. Then the treadle is brought down, and the shaft is drawn downso,that. the can will be held between `the plate K H and the base of thecavity d. As the copper block C contains the liquid solder in-its cavityd, into which the can isheld, the solder will be spread over the edge ofthe can as the saine is revolved by the 'action of the shaft D. Theblock C being hot heats the can, and the samewill therefore take up thesolder. The solder will also ow through crevices into the inside of thecan, and will thus solder the same from the insideV and outside. Thereservoir a should be kept lled by an automatic device, so :1s to havetbe solder always :it tbe saine level. The best device would be to havea, reservoir containing liquid solder above the reservoir zz, and to letthe solder How into the reservoir fr in a continuous but small stream,or in drops at regular intervals.

By this invention the tedious soldering by hand Will be overcome, andtin cans will be soldered with greater dispatch, regularity, `andaccuracy.

Having thus described my invention, I claim as new, and desire to secureby Letters Patent- 1. The plete A, provided with two recesses orreservoirs, a and b, for holding tbe solder-'and block C respectively,substantially as herein shown and described.

2. The block C, when made to it the recess in the plete A, and whenprovided `with a. recess or cavity, d, to'reeeive the edge ofthe cantolbe soldered, substantially as herein shown and described.

3. The arrangement of tlie recesses c ande, whereby the cavity din theblock()v is connected with the solder-reservoir a, substantii'rily asherein shown and described.
